Verfahren zur Verhinderung de8 Einsinkens von Polyamidspritzaüftrag auf VliesstoffMethod for preventing the sinking of polyamide injection onto nonwoven fabric
Es ist bereits "bekannt, Bekleidungsstücke mit Versteifungseinlagen zu versehen, um ihnen bessere Form und Standfestigkeit zu geben. Während man früher für diesen Zweck fast ausschließlich Roßhaareinlagen verwendete, setzen sich immer mehr die sog. Vliesstoffe durch. Man versteht darunter textile Faserflächengebilde, die an ihren Kreuzungspunkten miteinander verbunden sind. Unter den zahlreichen Herstellungsverfahren sei wahlweise nur auf dasjenige gemäß DP 920 211 verwiesen.It is already known to provide items of clothing with stiffening inserts to give them better shape and stability admit. While horsehair deposits were used almost exclusively for this purpose in the past, they always sit down more so-called nonwovens. This is understood to mean textile Fibers, which are connected to each other at their crossing points. Among the numerous manufacturing processes optionally only refer to the one according to DP 920 211.
um das langwierige Einnähers der Versteifungsstoffe in die Kleidungsstücke zu umgehen, wurde auch bereits vorgeschlagen, dieselben mit einem Klebepulver zu versehen, welches in der Hitze erweicht· Bei sog· einbügelbaren Versteifungsstoffen genügt es, die präparierte Einlage mit der Klebstoffseite auf das zu versteifende Gewebe aufzulegen und mit dem heißen Bügeleisen darüber zu fahren. Unter dem Druck und der Wärme werden beide Faserflächengebilde fest miteinander verbunden. Ein derartiges Verfahren ist z.B. aus der DAS 1 146 028 bekannt ,around the tedious sewing of the stiffening materials into the To bypass garments, it has also already been proposed to provide the same with an adhesive powder, which is in the Heat softens · With so-called · ironable stiffeners, it is sufficient to have the prepared insert with the adhesive side on put on the fabric to be stiffened and run over it with the hot iron. Under the pressure and the heat both fiber fabrics are firmly connected to one another. Such a method is known from DAS 1 146 028, for example ,

Man hat ferner auch schon versucht, Polyamid als Klebemittel auf Versteifungseinlagen aufzubringen. In diesem Fall wird man wegen des hohen Schmelz- bzw. Erweichungspunktes des Polyamids nicht aufsintern, sondern vielmehr eine Lösung des Polyamids aufsprühen. Man erhält dabei einen teils groben fadenförmigen, teils flächig feinen Spritzbelag je nach der Spritzbedingung, der wegen des hohen Lösungsmittelgehaltes jedoch teilweise in das Innere der Faserauflage einsickert. Da die Klebewirkung naturgemäß nur von denjenigen Anteilen des Klebemittels bewirkt werden kann, welche sich auf der Oberfläche befinden, bringt das Aufsprühen von Polyamid trotz mancher Vorteile gegenüber herkömmlich verwendeten Haftmassen die oben angeführten Nachteile mit sich. Sprüht man nämlich zu große Mengen auf, dann wird die an sich gewünschte Versteifung so groß, daß die Einlagestoffe für viele Zwecke unbrauchbar werden (Durchschlagerscheinungen)· Sprüht man dagegen zu wenig, ist der gewünschte Hafteffekt nicht ausr reichend.Attempts have also been made to apply polyamide as an adhesive to stiffening inserts. In this case it will because of the high melting or softening point of the polyamide not sintered, but rather a solution of the Spray on polyamide. A partly coarse, thread-like, partly flat, fine spray coating is obtained, depending on the Spray condition, which due to the high solvent content, however, partially seeps into the interior of the fiber layer. Since the adhesive effect can naturally only be brought about by those parts of the adhesive which are on the Surface, the spraying of polyamide brings despite some advantages compared to conventionally used Adhesive masses have the disadvantages listed above. If you spray on too large amounts, then the one you want will be Stiffening so great that the interlining materials are unusable for many purposes (breakdown phenomena) · Sprays on the other hand, if you do not do enough, the desired adhesive effect is not sufficient reaching.
Es wurde nun gefunden, daß man das unerwünschte Einsinken von Lösungen von Polyamid und anderen Verklebungsstoffen dadurch verhindern kann, daß man die Versteifungseinlage mit einem Oleophobierungsmittel behandelt. Besonders günstige Ergebnisse erzielt man bei Verwendung von Fluorcarbon-Harzen. Während im allgemeinen Gewebe mit solchen Mengen oleophobiert werden, daß eine Gewichtszunahme von 6 # resultiert, genügen im vorliegenden Pail bereits Mengen von 0,25 $>· It has now been found that the undesired sinking in of solutions of polyamide and other adhesive materials can be prevented by treating the stiffening insert with an oleophobic agent. Particularly favorable results are achieved when using fluorocarbon resins. While tissues are generally oleophized with such amounts that a weight increase of 6 # results, amounts of $ 0.25 are sufficient in the present package.
